Question

Professor PC Thomas Classes · Answer

The output of a rectifier will always have varying components. It is known as AC component. ACcomponent/DC component in the output is called ripple factor. It is a measure of the purity of the output.\ Half wave rectifier has a ripple factor $121 \%$. It means that the varying component is more than dc component. A half wave rectifier is used only for one purpose ie to charge battery.\ Ripple frequency is the number of ripples in the output side for one second\ For a half wave rectifier the ripple frequency $=$ input frequency\ For a full wave rectifier ripple frequency is equal to twice the input frequency.\
